The Pompey store will be celebrating the club's 125th anniversary with a range of new products.
The 'Portsmouth Retro Vault' is opening for three fan favourite retro shirts going on sale, all priced at £45.
The 1978-80 and the 1991-93 shirts will be available to purchase alongside mugs, keyrings and coasters of each one.
Blues fans will have fond memories of the 1978-80 jersey, which saw promotion from the fourth division in the second of those campaigns.
And the 1991-93 number, which was worn in the FA Cup semi-final against Liverpool at Highbury, is available to purchase once again.
Supporters will be able to pre-order the 1987/88 jersey online from 9am this Saturday (April 1).
The first wave of items will arrive in the shop ahead of the Forest Green fixture featuring the 125th anniversary club logo, from mugs and scarves to limited edition watches and glassware.
All three kits and products will be available to buy/pre-order online from 9am on Saturday, April 1, and the 1978-80 and 1991-93 shirts can be purchased in-store from 9am on Friday, March 31.
